cAn-DooR-SECURING MEANS.

Application and my 14, 1925. serial No. 43,643.

K `This invention relates toV car doors, and more particularly to .means for securing car. doors in closed position. v p

The invention has for one of its objects the provision of novel, simple and inexpensive means through the medium of which the cardoor forming the subjectmatter of our U. S. Letters Patent N o. 1,489,959, granted April 8, 1924, and other similar doors, can be secured in closed position with the outer sidesv of'their lateral edge portions in full abutting contact with` the inner surfaoesof the sides of the car.

The foregoing and other objects are attained by the construction, combination and arrangei'nent of parts hereinafter fully de'- scribed and claimed, and illustrated inthe accompanying drawings, wherein:

Figure 1 is a sectional View taken on a plane extending vertically and centrally through a fragmentary portion of a box car equipped with door securing means embody-v n ing our invention;

Figure 21s a sectional view taken on the l vertical plane indicated by the line 2-2 of Figure l;

Figure 3 is a sectional view taken on the horizontal plane indicated by the line 3-3 of Figure 1;

Figure 4 isa sectional view taken on the vertical plane indicated by the line 44 of Figure 1, and

Figure 5 is a sectional view taken on the horizontal plane indicated by the line 5 5 of Figure 1.

Corresponding and like parts are referred to in the following description, and designated in the several views of the accompanying drawings by similar reference characters. Y

In the drawings 1 designates the side of a box car which is provided with the usual door opening 2. A door 3 for closing the opening 2 is slidably suspended from a track 4 by hangers 5. The door 3 is provided with an opening which is adapted to be closed by a plate 7 whichis slidably supported on the door by a guide 8. A rod 9 is slidably mounted in brackets 10 secured to the door 3, and has its lower end .connected to the plate 7. A hand wheel 11 having threaded engagement with thek rod 9 and resting upon the upper bracket 10 provides means by which the plate 7 may be `raised to uncover' the opening 6 and lowered to close said opening. A strip 12 secured to the lower edge of the door 3 rests in the groove of a track 13 secured to the floor of the car. y

.Casings 14 are secured to the side 1 of the car adjacent the door posts-2a. The casings 14. are fully open at their inner sides, and the bottomv walls 15 thereof are inclined downwardly and inwardly to prevent foreign matter from accumulating within the casings. Bolts 16 which pass through the side 1v secure the casings 14 in place, and they are provided at their outer ends with nuts 17 and at their inner ends with heads 18. Metal strips 19 are positioned between the outer surface of the side 1 and the nuts 17 to prevent the strain on .the bolts 16 from pulling the nuts 17 into the side 1. Lock bolts 2O are pivoted to the heads 18 by pins 21. Nuts 22 provided with actuating levers 22a are carried bythe bolts 20. The

free ends of the bolts 20 are flanged over as into-contact with the keepers, the door 3 is firmly secured in closed position. When it is desired to open the door 3, it is only necessary to turn back the nuts 22 and swing the bolts 2() into the' casings 14. A stop 26 isadapted to limit the closing movement of the door and a stop 27 is adapted to limitv the opening movement thereof, and the door is provided with handlesv28 to permit of its being readily moved into opened or closed position. lVhen the door reaches its closed position as determined by 'the stop 26, the

slots 25 are in position to permit thebolts 2O to be swung into engagement with theV keepers 24. lhen the door 3 reaches opened vposition as ydetermined by the stop 27, twor of the keepers 24 will be positioned for engagement by two of the bolts 20. y

From the foregoing description, taken in connection with the accompanying drawings, it should be apparent that the securing means is adapted lto hold the door 3 in either closed or opened position and thatit will not. interfere with the movement of the door from closed to opened or from opened to closed position. It will also be apparent that.

the securing means isstrong, durable and eflicient, and that it may be readily secured to a. car. Y

`While We have described the principle of operation ofthe invention, together with the device which We now consider to be the best embodiment thereof, We desireA to have it understood that the device shown is merely illustrative, and that such changes may be made when desired as are Within the scope ot' the invention as claimed.

Vilhatis claimed is:

l. Car door securing means comprising a slotted keeper secured to the door, a retaining bolt secured to the car, a housing secured to the car by the retaining vbolt and having'an open side, a keeper-engaging bolt pivoted to the retaining bolt and located Wholly Within the housing when outv of engagement With the keeper and adapted to be swung through the open side of the housing into engagement with the keeper, and a keeper-contacting mit carried by the keeper-engaging bolt.

2. In combination, a car having an opening, a door for the opening, means supporting the door for horizontal sliding movement into opened and closed positions, keeper plates secured-to. the door and project-ing beyond the vertical edges thereof, bolts pivoted to the car adjacent the vertical Walls of the opening thereof and adapted to be engaged with the keeper plates when the door is closed, `certain of said bolts bei-ng adapted to be engaged with certain of said `keeper blades when the door is opened, and keepercontacting nuts carried byV the bolts. i

Intest-imony whereof We affix our signatures.
